To all whom it may concern:

Be it known that I, LEWIS RICHARDS, a subject of the Queen of Great Britain, residing at Dowlais, in the. county of Glamorgan, South Wales, Great Britain, engineer, have invented Improvements in Apparatus for'Straightening Railway-Rails, (for which I have obtained a patent in Great Britain, No. 5,145, dated October 30, 1882,) of which the following is a inan apparatus for straightening rails, of a rotary disk and a roller or rollers arranged opposite the face of the disk and adapted to rotate in a plane at right angles to the face of the disk, as hereinafter more fully described.

My invention therefore consists in a novel method of straightening rails, which involves subjecting the rail to pressure or force between devices which are arranged opposite each other, and which act upon opposite-sides of the rail at opposite points. For straightening rails by this method I may employ rolling devices, such as two disks having their axes parallel or in line, or a disk and a roller having its axis transverse to the axis of the disk and arranged opposite the face of the disk; or I may employ an anvil and a hammer or striker adapted to operate on the side of the rail opposite that which rests on the anvil.

The invention, therefore, also consists in a method of straightening rails which involves subj ecting the rail to pressure between rolling or rotary devices which are arranged opposite each other, and which act on opposite sides of the rail at opposite points.

The invention also consists in the combination, in an apparatus for straightening rails,

of a rotary disk and a'roller or rollers ar- Batented in England October 30, 1882, No. 5,145. 7

ing my invention.

Figures 1 and Z represent in elevation and plan an arrangement in which the straightening of the rail is effected by passing the rail between rollers movable under pressure or fixed at the proper distance, and revolving disks.

ing-wheel, F, on the same shaft between them. H H are the rollers, arrangedopposite the faces of the disks 0 O, and adapted to rotate in planes at right angles to the faces of the disks, so as to press the rail I against the outer face of the disks. The rollers H Hmay run either loosely or be driven by suitable gear, and they may be fixed at the proper distance to suit the section of rail to be operated upon; or they may be movableand be pressed forward toward the face of the disks 0 O by. means of hydraulic power, as shown at A, or by other suitable means; and the rail is to be straightened as required-on the flat on one its depth, on the other disk-by its being placed as shown and being passed between the roll-- ers and the face of the disk.-

Figs. 3 and 4 represent in elevation and plan an arrangement in which the disks and rollers with the pressing apparatus are caused to operate on the rail in both ways or directions simultaneously. In Fig. 4 the rollers actremoved. On reference to these figures it will be-seen that the disks 0 O and the rollers. H H are arranged so as to act both horizontally and'vertically-on the rail as it is passed between them, as shown more particularly in the elevation, Fig. 3. It will be seen, also, that the parts are combined in such a manner as to be more ooncentrated in their united action on the rail than in the previous arrangement.

Figs. 5 and 6 are views of an arrangement in which the rail is operated upon on different sides simultaneously by two disks, 0 0, ar-- somewhat from one another, but all embody- 0-0 are two revolving disks, with a drivdisk, and 'on the edge, or in the direction of ing on the side of the rail are supposed to be 'there is comprised a rotary disk and a roller or rollers arranged opposite the face of the I 5 disk and adapted to rotate in a plane at right angles to the face of the disk.

I claim as of my invention The combination, in an apparatus for straightening rails, of a rotary disk and a 20 roller or rollers arranged opposite the face of the disk and adapted to rotate in a plane at right angles to the face of the disk, substantially as herein described.

LEWIS RICHARDS.
